Materials Data on KCuTe by Materials Project
KCuTe crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. K1+ is bonded to six equivalent Te2- atoms to form a mixture of distorted edge, corner, and face-sharing KTe6 octahedra. The corner-sharing octahedral tilt angles are 42°. All K–Te bond lengths are 3.62 Å. Cu1+ is bonded in a trigonal planar geometry to three equivalent Te2- atoms. All Cu–Te bond lengths are 2.58 Å. Te2- is bonded in a 3-coordinate geometry to six equivalent K1+ and three equivalent Cu1+ atoms.
